Description

本考案は、椅子に関する。 The present invention relates to a chair.

一般に、椅子は、材料で分類すると、木材製、樹脂製または金属製などがある。椅子に使用する材料が異なると、その椅子の構成も異なる。木材製の椅子は、重量がやや重く、製造が簡単でなく、又、製造コストが高い。又、樹木伐採は環境を悪化させるので、材料の調達は日増しに困難な状況になりつつある。そのため、大量生産は困難となることから、近年、椅子は樹脂や金属等の材料から作られる傾向にある。 Generally, chairs are classified into materials such as wood, resin or metal. If the material used for the chair is different, the configuration of the chair is also different. Wood chairs are somewhat heavy, not easy to manufacture, and expensive to manufacture. In addition, tree cutting worsens the environment, and the procurement of materials is becoming increasingly difficult day by day. Therefore, mass production becomes difficult, and in recent years, chairs tend to be made of materials such as resin and metal.

ところが、樹脂や金属から作られる椅子は、座体と肘かけと背もたれとが別々に作られてから相互に組み合わせられるものが多いため、組み合わせに時間がかかり、製造コストが高くなるという問題があった。
また、座体と肘かけと背もたれとが別々に作られると、それらが他の部品で連結されたとしても椅子全体としての強度が低いという問題があった。 However, many chairs made of resin or metal can be combined with each other after the seat, armrest, and backrest are made separately. It was.
Further, when the seat body, the armrest, and the backrest are made separately, there is a problem that the strength of the entire chair is low even if they are connected by other parts.

本考案は、このような点に鑑みてなされたものであり、その目的は、製造工程を短縮することができ、且つ、高い強度を持つ椅子を提供することにある。 This invention is made | formed in view of such a point, The objective is to provide the chair which can shorten a manufacturing process and has high intensity | strength.

本考案による椅子は、座部、脚部、及び、脚部を座部の底に固定する固定手段を備える。座部は、座体と２つの肘かけと背もたれとが例えば樹脂から一体に形成されてなる。座部は、例えば射出成形で作られる。座部の肘かけは、座体の左右両側の縁から上方に延びるように形成され、背もたれは、両肘かけの上端部同士を互いに接続するように形成される。背もたれは、座体に連結することなしに肘かけだけに連結される。背もたれは、両肘かけ間に渡されるように設けられ、座体との間に空間を形成する。 The chair according to the present invention includes a seat portion, a leg portion, and fixing means for fixing the leg portion to the bottom of the seat portion. The seat portion is formed by integrally forming a seat body, two armrests, and a backrest, for example, from a resin. The seat is made, for example, by injection molding. The armrest of the seat is formed so as to extend upward from the left and right edges of the seat, and the backrest is formed so as to connect the upper ends of both armrests to each other. The backrest is connected only to the armrest without connecting to the seat. The backrest is provided so as to be passed between the armrests, and forms a space between the backrest and the seat.

このような椅子によれば、背もたれが座体に連結せず、肘かけに連結され、背もたれと座体との間に空間が空けられることで、背もたれに適度な弾性を持たせることができる。
また、座部は、座体と肘かけと背もたれとが樹脂から一体に形成されるので、高い強度が得られるとともに、製造過程の一工程で座体と肘かけと背もたれとを同時に作ることができるので生産速度を上げることができ、製造コストを安くすることができる。 According to such a chair, the backrest is not connected to the seat body, but is connected to the armrest, and a space is made between the backrest and the seat body, so that the backrest can have appropriate elasticity.
In addition, since the seat, armrest, and backrest are integrally formed from resin, the seat can be made with high strength, and the seat, armrest, and backrest can be made simultaneously in one step of the manufacturing process. Therefore, the production speed can be increased and the manufacturing cost can be reduced.

以下、本考案の複数の実施形態を図面に基づいて説明する。実施形態同士で実質的に同一の構成には同一の符号を付して説明を省略する。
図１〜図８に示すように、本考案の第１実施形態による椅子は、座部１と、固定手段２と、脚部３とから構成される。 Hereinafter, a plurality of embodiments of the present invention will be described with reference to the drawings. In the embodiments, substantially the same components are denoted by the same reference numerals and description thereof is omitted.
As shown in FIGS. 1-8, the chair by 1st Embodiment of this invention is comprised from the seat part 1, the fixing means 2, and the leg part 3. As shown in FIG.

座部１は、座体１１と、２つの肘かけ１２と、背もたれ１３とを有する。座部１２は、耐食性と耐衝撃性を持つ非金属材料、例えば樹脂、合成樹脂、プラスチックスチール、再生樹脂、又は、再生合成樹脂等から作られる。 The seat 1 has a seat body 11, two armrests 12, and a backrest 13. The seat portion 12 is made of a nonmetallic material having corrosion resistance and impact resistance, such as resin, synthetic resin, plastic steel, recycled resin, or recycled synthetic resin.

座体１１は、その底部の中央部に上下に延びる複数のねじ穴１０を有する。このねじ穴１０には、脚部３を座体１１に固定するための図示しないねじが締め付けられる。
肘かけ１２は、座体１１の左側または右側の縁から上方に延びるように形成される支持部、及び、その支持部の上端から後方に延びる肘かけ部を有する。肘かけ１２の支持部の前縁と座体１１との傾斜角度１２１Ａは９０度より小さくされる。また、肘かけ１２の支持部の後縁と座体１２との傾斜角度１２２Ａは９０度よりも大きくされる。 The seat body 11 has a plurality of screw holes 10 extending vertically in the center of the bottom thereof. A screw (not shown) for fixing the leg portion 3 to the seat body 11 is tightened in the screw hole 10.
The armrest 12 has a support portion formed so as to extend upward from the left or right edge of the seat body 11, and an armrest portion extending rearward from the upper end of the support portion. An inclination angle 121A between the front edge of the support portion of the armrest 12 and the seat body 11 is made smaller than 90 degrees. Further, the inclination angle 122A between the rear edge of the support portion of the armrest 12 and the seat body 12 is set to be larger than 90 degrees.

また、肘かけ１２の支持部の後縁１２２と肘かけ部の下縁との角部１４が円弧状に形成され、肘かけ１２の肘かけ部の後端は、後方に延び、背もたれ１３の下縁と連結される。これにより、背もたれ１３は、一対の肘かけ１２を介して座体１１と一体に形成される。背もたれ１３は、両肘かけ１２の間に渡されるように設けられ、ある程度の弾性を自然に生じる。椅子に人が座り、背中が背もたれ１３に寄りかかった時、背もたれ１３は多少の弾性を持つので、座る人は座り心地が良くなる。 In addition, a corner portion 14 between the rear edge 122 of the support portion of the armrest 12 and the lower edge of the armrest portion is formed in an arc shape, and the rear end of the armrest portion of the armrest 12 extends rearward, and the backrest 13 Connected with the lower edge. Thereby, the backrest 13 is formed integrally with the seat body 11 via the pair of armrests 12. The backrest 13 is provided so as to be passed between the armrests 12, and naturally generates a certain degree of elasticity. When a person sits on a chair and the back leans against the backrest 13, the backrest 13 has some elasticity, so that the sitting person becomes comfortable.

図８に示すように、固定金具２は固定板と挟み部材２１とを有する。座部１と脚部３とを互いに組み合わせるとき、脚部３の上部の二本の平行棒が固定手段２の固定板と挟み部材２１とに上下に挟まれてから、座体１１の底部の中央部に図示しないねじで固定される。 As shown in FIG. 8, the fixing bracket 2 includes a fixing plate and a sandwiching member 21. When the seat portion 1 and the leg portion 3 are combined with each other, the two parallel bars on the upper portion of the leg portion 3 are vertically sandwiched between the fixing plate of the fixing means 2 and the sandwiching member 21, and then the center of the bottom portion of the seat body 11 is placed. It is fixed to the part with a screw (not shown).

座部１は、図７に示すような形式の脚部３の他に、図９に示すような脚部３（第２実施形態）、図１０に示すような脚部３（第３実施形態）、及び、図１１に示すような脚部３（第４実施形態）にも組み合わせて椅子を構成することができる。 In addition to the legs 3 of the type shown in FIG. 7, the seat part 1 includes the legs 3 as shown in FIG. 9 (second embodiment) and the legs 3 as shown in FIG. 10 (third embodiment). ) And a leg 3 (fourth embodiment) as shown in FIG. 11 can be combined to form a chair.
